Tamra Barney was
Andy Cohen's guest on
"Watch What Happens Live" Tuesday (May 1), but it was during the
"After Show" that she brought out a couple of guests of her own -- her new implant-free boobs.

A 23-year-old woman considering breast augmentation calls in to the show to ask for Tamra's advice on getting implants. Tamra's surgery to
remove her implants and go back to her natural 34B size was documented this season on
"The Real Housewives of Orange County."

As Tamra's attempting to persuade the woman not to get implants, Andy starts to throw in his two cents about how he loves "big tits," leading Tamra to flash her breasts to a super-surprised Andy.

"Tamra just showed me her bare breasts, and they look great and they are a perfect size," he says blushing. "I do love big tits, and I have been to strip clubs and I do not like what big, fake boobs look like."

Check out the video below (no, you don't actually see her boobs). The big flashing moment is at the 7:17 mark.
